Product details

The ±25 ppm frequency stability keeps CAN, LIN, and 10/100 Ethernet PHY clocking within tolerance without external compensation.

It is suitable for under-hood and chassis-domain applications where a standard commercial oscillator would risk field failures. Supply voltage range is 2.25 V to 3.6 V, covering 2.5 V and 3.3 V rails with margin. At 24 MHz, max supply current is 35 mA; the disable function drops it to 22 mA — useful for power-save modes in battery-backed modules.

This is a current-design-in part, suitable for both new builds and volume production.

6-SMD no-lead package, 3.20 mm x 2.50 mm footprint, 0.90 mm seated height. The compact footprint leaves room for decoupling caps near the supply pin.

Frequently asked questions

Is DSC1121CI2-024.0000T AEC-Q100 qualified?

Yes, it carries AEC-Q100 rating. That means it passed automotive-grade qualification: temperature cycling, ESD, latch-up, and extended life tests. Suitable for under-hood and chassis-domain designs.

What is the frequency stability of DSC1121CI2-024.0000T?

Tight enough for CAN, LIN, and 10/100 Ethernet PHY clocking without external trimming.
